yfinance not working - receiving json.decoder.JSONDecodeError


I am scraping stock market data from yfinance. My code worked perfectly during the last weeks. For some reason, now I am receiving the following error:

json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

when executing:

import yfinance as yf
tsla_df = yf.download('TSLA', start='2020-01-01', end='2021-01-01', progress=False)

I have read about this error on Stack Overflow, but no one had an appropriate solution to fix the problem. I am wondering because this simple code worked well days ago. So maybe there is a general problem with the yfinance API at the moment? Can anyone confirm or has a solution for this problem?
